CARBURETING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 246,601, dated September 6, 1881,

Application filed April .27, 1881.

To all whom it may concern:

Be it known that I, CHARLES F. COPELAND, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in CarburetingApparatus, of which the following description, in connection with the accompanying drawings, is a specification.

My invention relates to an apparatus for ca rbureting air or ordinary illuminating-gas by charging it with the vapor of naphtha or other volatile hydrocarbon, and is shown embodied in that class of apparatus in which the air or gas is received in a perforated pipe or passage embedded in absorbent material, which is kept saturated with the hydrocarbon liquid, which is delivered throughout the entire extent of the said absorbent by suitable distributing or spreading apparatus.

In apparatus of this kind it has usually been attempted to charge the gas as fully as possible with the vapor, and it frequently becomes overcharged, and the vapor consequentlycondenses in the pipes, and thus interferes with the proper flow of the gas.

This is obviated by my invention, which consists, mainly, in providing a purifying-chamber through which the charged gas has to pass after issuing from the absorbent material before entering the deliverin g-pipes, and in which the surplus vapor is condensed and returned to the absorbent material. The said chamber has perforated walls to permit the flow of gas therethrough, andis filled with asbestus,which, from its fibrous nature, acts upon to purify the said gas and condense out or remove any surplus vapor, but only acts slightly as an absorbent, and consequently allows the condensed liquid to settle or fall by the action of gravity into the absorbent material below. The perforated pipe from which the gas is introduced to the absorbent material is surrounded with wicking wound around it, in addition to the saw-dust commonly used as the absorbent and usually filling the entire space around the said pipe.

Figure l is a top or plan view of a carbureting apparatus, the top or cover portion being removed to show the purifying-chamber; Fig. 2, a similar view with the purifying-chamber and absorbent material removed to show the parts below; Fig. 3, a longitudinal section on (No model.)

line 00 ac, Fig. 1, and Figs. 4. and 5 a side elevation and top view of a portion of the perforated pipe from which the gas passes to the absorbent material.

The carburetingchamber a, of any suitable or usual construction, contains the gas or air receiving passage 1), connected with the gas-inlet 0, and winding back and forth across the bottom of the chamber a, in order to introduce the gas in every part thereof. The passage 1) is made rectangular in cross-section, as shown in Fig. 3, and consists merely of a top and two sides, resting at their lower edges upon the bottom of the chamber a, which thus forms the bottom of or closes the said passage b, the sides of which are perforated, as shown in Figs. 3 and 4, to permit the gas to escape into the bed d of absorbent, in passing through which it is charged with vapor in the usual manner. The charged gas, upon rising from the absorb ent, has to pass through the purifying-chamber e, resting upon and completely covering the the said chamber being perforated, as shown in Fig. 3. A portion only of the said perforations are shown at 2 in Fig. l, for the sake of simplicity, it being, however, understood that the said perforations extend over the entire surface. The purit'ying-chamber c is filled with loose asbestus, as shown in Fig. 3, which serves to clean the gas and remove the vapor in excess of what can be properly carried by the gas, and which would otherwise be likely to condense in and obstruct the pipes. The gas, after passing through the purifying-chamber e, collects in the top of the carbureting-chamher a, whence it is led off by the delivery-pipe f, to be consumed. The hydrocarbon liquid, with the vapor of which the gas is to be charged, is introduced from any suitable or usual receptacle through the pipe g, controlled by thevalve It, automatically operated by the float i in the usual manner. The liquid entering through the valve it passes into the channel m, lying just beneath the purifying-chamber e, which may have a recess in its lower portion, as indicated by dotted lines 3, Fig. l, for the reception of the said channel m, which is provided with holes or passages 4, through which the liquid descends into the distributing channels a, lying above the gas-receiving passage 1), and

said absorbent, the upper and lower walls of embedded in the absorbent d. The function of these channels, arranged in this manner, is to cause theliqnid flowing in through the channel m and passages 4 to first fill the channels n from end to end, after which, in overflowing the said channels a, it permeates the entire bed d of absorbent, but is delivered directly along the perforated sides of the passage 1), lying directly beneath and in line with the said edges of the channels a, as shown in Fig. 3.

The float t' operates in the usual manner to prevent the complete saturation of the bed (1 above the level of and so as to close by the body of liquid the perforations in the sides of the passage 1).

I have discovered that by surrounding the passage 1) with wicking, as shown in Figs. 3 and 5, a much better effect is produced than when the coarse sawdust or the material of which the bed d is usually made lies directly against the walls of the said passage.

I claim 1. In a carbureting apparatus, the perforated gas-receiving passage, and liquid-distributing channels thereon, embedded in absorbent material, and the liquid-introducing channels and passages therefrom into the said distributing-channels, the said devices being arranged in combination, as described, whereby the liquid in its passage to the absorbent material will he delivered directly along the perforated faces of the said gas-recehing passage, substantially as described.

2. In a carbureting apparatus, the gasreceiving passage and liquid-distributing devices and absorbent bed therefor, combined with the purifying-chamber located above the said bed, between the said liquid-distributin g devices and the delivery-passage for the carbureted gas, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES F. COPELAND.
